- The 8085’s register file reverse engineered (righto.com)
On the surface, a microprocessor’s registers seem like simple storage, but not in the 8085 microprocessor. Reverse-engineering the 8085 reveals many interesting tricks that make the registers fast and compact. The picture below shows that the registers and associated control circuitry occupy a large fraction of the chip, so efficiency is important. Each bit is implemented with a surprisingly compact circuit. The instruction set is designed to make register accesses efficient. An indirection trick allows quick register exchanges. Many register operations use the unexpected but efficient data path of going through the ALU.

Latvia (/ˈlætviə/ LAT-vee-ə, sometimes /ˈlɑːtviə/ LAHT-vee-ə; Latvian: Latvija Latvian pronunciation: [ˈlatvija]; Latgalian: Latveja; Livonian: Lețmō), officially the Republic of Latvia (Latvian: Latvijas Republika, Latgalian: Latvejas Republika, Livonian: Lețmō Vabāmō), is a country in the Baltic region of Northern Europe. It is one of the three Baltic states, along with Estonia to the north and Lithuania to the south. It borders Russia to the east, Belarus to the southeast, and shares a maritime border with Sweden to the west. Latvia covers an area of 64,589 km2 (24,938 sq mi), with a population of 1.9 million. The country has a temperate seasonal climate. Its capital and largest city is Riga. Latvians belong to the ethnolinguistic group of the Balts and speak Latvian, one of the only two surviving Baltic languages. Russians are the most prominent minority in the country, at almost a quarter of the population.
